Title: Laminating method of polymer sheet
Inventor: WATANABE KAZUO
IPC: B29C43/20
Filed: 1990-11-02
Abstract: PURPOSE:To obtain a thick, rolled, high strength polymer sheet by a method wherein a plurality of polymer films or sheets, each of which is uniaxially stretched by rolling and which are brought into a condition being interposed by adhesive film layer, and heated, compressed, fixed together by pressure and finally cooled by being pinched between the tools, each of which has heating and cooling devices, of presses. CONSTITUTION:Uniaxially stretched films 9, each of which is cut in a predetermined length, are stacked in advance to one another under a condition that the drawing directions of the films are set in the same direction or in the alternate directions with one another through adhesive film 10. next, the stacked films are pinched under the comparatively low pressure between presses 13, each of which has a tool 11 heated up to a predetermined temperature with a built-in heater 12. When the stacked films reach the temperature, which is lower than the melting point of the matrix of the film and higher than the melting point of the adhesive film layer and is held for a certain period of time so as to bring whole films to the predetermined temperature, pressure is increased so as to fix the stacked films by pressure. Further, simultaneously with or a little before the pressuring, heating is stopped and the cooling of the material or the films is performed by running cooling water in the interior of a pipe provided near the surface and in the interior of the tools.
